Measurement uncertainly evaluation at the choice of optimum amount of measuring and class of exactness of facilities of measuring

In work the states of problem of choice of class exactness of facilities of measuring technique are considered at the technical control of parameters of quality of products. The short analysis and estimation of domestic and foreign normatively technical document and recommendations on choice is conducted facilities of measuring.Procedure of estimation of uncertainly of arising up is considered at the choice of optimum amount of measuring and class of exactness of controls. As the criteria of optimization offered index of informative efficiency and having a special purpose function of cost of implementation of measuring. Results can be uses in the work of metrological services of enterprises at planning and organization of control and measuring operations.
